Airplane Passengers May Receive Sizable Dose of Radiation from Dark Lightning during Thunderstorms

“What are the radiation doses to airplane passengers from the intense bursts of gamma-rays that originate from thunderclouds?" Florida Institute of Technology Department of Physics and Space Science faculty members will address the issue and present their modeling work at a press conference meeting of the European Geosciences Union in Vienna, Austria, April 10. Joseph Dwyer, Ningyu Liu and Hamid Rassoul will discuss a new physics-based model of radiation dose calculations and compare the calculations to previous work.

New Cryogenic Current Comparator Along with Quantum Hall Effect Allows Precise Measurement of Resistance

Cryogenic Ltd and the National Physical Laboratory (NPL) have designed and developed the most accurate instrument for comparative measurements of electric current. The instrument can now be used by National Measurement Institutes (NMI) and laboratories around the world, providing a more accurate standard for current ratio, and ensuring current measurement is not a limiting factor in innovation.

Novel Photonic Floquet Topological Insulator Developed at Technion

Researchers at the Technion-Israel Institute of Technology have developed and successfully demonstrated a photonic Floquet topological insulator, a new device used to protect the transport of light through a unique, lattice of 'waveguides.' The advancement may play a key role in the photonics industry. A description is published in the current issue of NATURE (11 April 2013).

If Quantum Physics Weren't Uncertain We Could Achieve Perpetual Motion

"…if your theory is found to be against the second law of thermodynamics I can give you no hope; there is nothing for it but to collapse in deepest humiliation" said the British astrophysicist Sir Arthur Eddington in the early 1900s. He was on to something. CQT researchers Stephanie Wehner and Esther Hänggi report in Nature Communications that obedience to the second law of thermodynamics could lie behind one of the most fundamental features of quantum physics: the uncertainty principle.

Suzaku Satellite's X-ray Imaging Spectrometer Reveals Remnant of Kepler's Supernova

An exploding star observed in 1604 by the German astronomer Johannes Kepler held a greater fraction of heavy elements than the sun, according to an analysis of X-ray observations from the Japan-led Suzaku satellite. The findings will help astronomers better understand the diversity of type Ia supernovae, an important class of stellar explosion used in probing the distant universe.

Researchers Propose Using the International Space Station to Test Quantum Entanglement

Albert Einstein famously described quantum entanglement as "spooky action at distance"; however, up until now experiments that examine this peculiar aspect of physics have been limited to relatively small distances on Earth.
